5000 Series T 3 is the ultimate in direct replacement 2 piece performance brake rotors Featuring all the benefits of the 5000 Series along with DBA’s patented world-renowned T 3 bi-directional slot design.

Built on the foundations of DBA’s T 2 slot, the T 3 slot design features additional precise CNC machined tri symmetrical slots, resulting in an even quieter, more responsive, and smoother braking experience. The T3 slot increases the number of exit points for brake pad friction dust and gases to escape through, further increasing the consistency and effectiveness of every brake stop.

DBA recommends a T3 slot for high-performance applications.

DBA's 4000 Series T3 rotors feature our best technology and materials for maximum performance. High carbon & heat-treated iron, patented Kangaroo Paw ventilation and Tri-symmetrical slotting make for the perfect direct replacement rotor.

  • Rotors are crafted from alloyed iron with a high carbon content to achieve low levels of vibration and squealing under the hottest conditions
  • 48 curved slots in the rotor surface give aggressive brake pad bite and offer the best management of the high heat, dust, and gasses that build up during racing
  • Rotors are treated with a patented Thermal Stability Process to reduce metal stress which weakens iron over many heating and cooling cycles
  • Paint on all non-contact rotor areas provides corrosion resistance
  • "Kangaroo Paw" design features 144 spaced pillars between the inner and outer faces of each rotor that provide faster cooling and greater strength than traditional slotted cooling fins
  • Lower rotor temperatures greatly reduce rotor warpage and boiling brake fluid which causes pedal fade
  • Manufacturer warranties rotors for 12 months or 12,000 miles
